Bringing advanced water filtration to commercial infrastructure DuPont launches TapTec™ LC HF-4040 17 November 2021, - DuPont (NYSE:DD)- DuPont Water Solutions (DWS) launched DuPont™ TapTec™ LC HF-4040 Reverse Osmosis (RO) membrane filter. Compact, affordable, highly reliable and effective, this product combines advanced features such as high flow rates, with reliability and ease-of-use. Reverse osmosis is the “go-to” solution for large, centralized water treatment and desalination plants.The membrane elements used there demonstrate a high water recovery rate and successful rejection of contaminants like salts. As DuPont, we support water producers with our membrane technologies. We are one of the biggest water technology companies in the world, DuPont water technologies process 25 million gallons (95 million liters) of water every minute around the world. Beyond the large-scale utility water systems that serve us, however, there is a tremendous need for effective and efficient water purification at point-of-use, especially in office buildings, restaurants, hotels and resorts. One of the big challenges there is the cost-effectiveness and ease-of-use of advanced water treatment technologies. To bring the advantages of large-scale reverse osmosis (RO) membrane filtration to more decentralized and commercial infrastructure use, we have launched the DuPont™ TapTec™ LC HF-4040 RO membrane filter. Compact, affordable, highly reliable and effective, this product combines advanced features such as high flow rates, with reliability and ease-of-use. The membrane elements are spiral-wound from a polyamide thin-film composite. They perform at an average flow rate of 2,800 gallons per day (10.6 m3/d) and have a minimum salt rejection of 98.5% *. As such they are ideally suited to provide affordable drinking quality water on site as part of an engineered system that can be designed for a variety of automation needs.
